wait for the 2020 march.
bitcoin is halving and it will be at least 3x.
now it can swing between 4000/5000. buy under 4000 and hodl until 2020 may
Maybe for some people is still very convinced to buy with bitcoin price now. but for me, buy now there is still a risk, because now we could see the price decrease experienced some bitcoin, but not so great. for large traders may still assume this is reasonable.
